Definitions
- the sensor devices are used, for example, the distance or speed measurement ⁇ and comprise for this purpose in particular at least one transmitting unit for emitting light or electromagnetic radiation, for example in
- Infrared area in an observation room, and at least one receiving unit for receiving the reflected light to / from objects in the observation room.
- Sensor devices are typically behind an inclined transparent disk, such as a glass sheet. the windshield, attached.
- distance sensors in particular a CV sensor (closing velocity sensor), e.g. in the context of avoiding rear-end collisions in a limited speed range or adapting one's own speed to a preceding vehicle
- the intensity of reflected light is used to qualify an object (also referred to as a target) in the observation room as a relevant obstacle (relevant object) or to evaluate.
- the light emitted by the sensor device is at least partially emitted by ice effects on the disk in directions which are not in the original and intended transmission range of the sensor device.
- This effect is also called a scattered light effect.
- reflect light effects for example, reflectors, which are attached to the ceilings of parking garages or underpasses, as relevant obstacles are interpreted, even if they are not in the driving path (in the driving way) of the vehicle. They generate so-called false positives, ie events which are a driver assistance system, for example an ACC system (Adaptive / Active Cruise Control) and / or a
- ACC system Adaptive / Active Cruise Control
- a significant feature of the scattered light effects is that the intensity of the, in particular of fake objects, reflected light majority is just above the relevance threshold to lie, ie above the threshold above which an object, due to the intensity of the reflected light is qualified as a relevant obstacle .
- One way of at least partially suppressing or avoiding such scattered light effects due to an icy disc is to estimate by means of suitable methods or devices, whether in principle the likelihood of an icy disc exists.
- the relevance or intensity threshold which must be exceeded by the reflected light, so that an object or a target of the sensor device or a downstream evaluation unit is evaluated as a relevant object, for example set higher for negative temperature values, so that the false positives from scattering (ie due to scattered light effects) are mostly hidden or not qualified as relevant objects.
- the change of one or more intensity thresholds of the sensor device is accompanied in particular a general reduction of the sensitivity of the sensor device, which ultimately reduces the applications that are solved sufficiently well.
- Use cases are, for example, cases in which, due to an obstacle detected by the sensor device, the vehicle is braked automatically, in particular by a brake assistant.
- an optimally solved application is, for example, given when the automatically braked vehicle comes to a standstill at a pre-defined distance to the obstacle.
- the predefined distance may be 0.5 to 1 m, depending on the speed range in which the braking was performed.
- a suitably well-solved application is preferably the case when it comes to an automatic braking to no contact with the obstacle, but the previously defined distances can no longer be met. For example, at a speed of 20 km / h, ie at a speed of 20 km / h, the vehicle may not stop 90 cm before the obstacle, but only 20 cm before it. The case (application) is still good or in this case solved well enough (there was no collision), but the desired distance could not be met at the end of the braking intervention.
- relevance thresholds are used as long as the outside temperature indicates negative temperature values.
- the less sensitive calibration is started at negative temperatures and held only for a certain time.
- the invention is based on the object, a method and an apparatus for a robust and reliable detection of ice or the probability of ice on one
- An essential idea of the invention is to use a temperature signal for detecting an iced slice or for detecting the probability of ice on the disc, in which case the temperature signal of at least one temperature sensor is used in the sensor device, for example in a one Lidar or radar sensor, already present or integrated.
- the sensor device is arranged on or in the vicinity of the window of a vehicle.
- the temperature sensor is thus preferably a temperature sensor already integrated in the sensor device.
- the internal temperature sensor which is already integrated in the sensor device can essentially be used for the purpose of measuring the operating temperature of the sensor device and thus in particular for avoiding overheating of the sensor device during operation in the sensor device
- Sensor device may be integrated, wherein overheating is avoided for example by adjusting the intensity and / or amplitude and / or frequency of the emitted radiation based on the temperature signal of the at least one internal temperature sensor or a cooling device is provided.
- the temperature signal which is used according to the invention for detecting ice or the probability of ice on a vehicle window, is thus generated by means of at least one temperature sensor, which is arranged or integrated on a circuit board of the sensor device, for example the internal temperature sensor, as already described above, essentially arranged from another problem or to fulfill at least one other function in the sensor device, in particular for detecting whether the sensor interior ambience exceeds high temperatures (avoiding overheating).
- the sensor device can also be more than just an internal temperature sensor, in particular for monitoring the
- Operating temperature include.
- the temperature signals of the several internal temperature sensors can be used to detect ice or ice likelihood.
- the proposed solution of using the internal temperature signal of the sensor device on the presence or the probability of ice on the vehicle window has the advantage that the temperature is measured directly where the sensor device is located in the vehicle and looking through the vehicle window , namely directly in the housing of the sensor device and immediately behind the windshield section, is emitted by the light and reflected light is received. Due to the fact that the temperature sensor is integrated in the sensor device anyway, costs, for example compared to solutions with the arrangement of an additional (external) temperature sensor, can be saved. The advantage of the inventive use of the internal or integrated temperature sensor over the use of an external temperature information remains in the fact that the internal temperature reproduces the reality of the ice-free in front of the sensor device much better.
- An external temperature sensor may be located very far away from the sensor device, eg in one of the rearview mirrors, and indicate negative temperatures when the range of the Vehicle window, behind which the sensor device is arranged, is already free of ice. With the internal temperature, the actual situation can be detected much more realistically, since with internal temperatures greater than the freezing point, the probability is high that the sensor device or the relevant area of the vehicle window is free of ice.
- the internal temperature signal can be used in particular at the time of starting the vehicle. This essentially has the advantage that, when starting the engine, the operating temperature of the sensor device has little or no effect on the temperature detected by the at least one internal temperature sensor and also indicates this at negative external temperatures at the time of starting the vehicle.
- the temperature in the sensor housing of the sensor device generally increases and can also assume positive values with continuous negative outside temperatures.
- the internal warming in the sensor housing and the driver behavior of the driver over time lead to the ice disappearing in front of the sensor device on the windshield, for example by activating an interior heating system or a windshield wiper system.
- the sensor device is then preferably started with a so-called winter calibration when the internal temperature sensor has a temperature below zero degrees (° C.) or a temperature slightly above zero degrees (eg 1, 2 or 3 ° C.), in particular when starting the engine, measures.
- the winter calibration preferably causes one or more detection thresholds (intensity or
- Threshold values for example for the intensity of the reflected light, at which a reflective object is evaluated as a relevant obstacle.
- the sensor device may after a settable time (eg, three, four, five, or more minutes) respond to a normal calibration (e.g., an ice-free vehicle window calibration) and thus to normal
- Detection thresholds for relevant objects in the signal processing are switched, in particular if the temperature determined by the internal temperature sensor the freezing point or a certain positive
- Temperature threshold e.g., 2 or 3 ° C or 4 or 5 ° C.
- the internal temperature signal a) Use of the internal temperature sensor or the internal temperature signal of a sensor device to detect whether there is frost when starting the vehicle or when starting to drive (eg temperatures ⁇ 0 ° C, ⁇ 3 ° C, ⁇ 4 ° C) and whether the probability of ice on the vehicle window is high. If the vehicle is started at negative temperatures, follows the application of one or more elevated detection thresholds for a certain period of time.
- the period of time for which the one or more elevated detection thresholds are applied may be formed as a constant value and / or as a function in particular of the starting temperature.
- the time duration for example as a function of the starting temperature, it is possible to proceed in such a way that the lower the internal temperature signal at the time of commissioning of the vehicle or of the system, the longer the time duration for the increased detection thresholds.
- ⁇ increased Detektionssc wave ⁇ f (Tzum Star time punk / wherein terhöhte detection threshold, the time period for the application of the increased detection threshold and T at the starting time refers to the temperature measured at the time of system startup internally. b) using the internal temperature sensor and the internal temperature signal as in point a). If the vehicle is started at negative temperatures or at temperatures just above zero degrees, the application of an increased detection thresholds for a certain period of time and until a positive temperature is exceeded or a positive temperature signal is generated (eg temperature greater than 0 ° C or 1 ° C or 2 ° C or 3 ° C or 4 ° C). c) Use of the internal temperature sensor or the internal temperature signal as under a) or b).
- the use of Support points is particularly advantageous if the temperature sensor is not a linear representation of the real temperature.
- the method with interpolation points can be represented according to FIG. 1 with interpolation points T1 to T6 and the imaging curve ABK of the temperature sensor.
- the internal temperature of the sensor device in particular after previously exceeding the freezing point during operation, falls (again) below a lower temperature threshold and the internal temperature sensor provides a corresponding internal temperature signal, for example at temperatures below zero degrees (° C), then preferably (again) switched back to the calibration with the increased detection thresholds for relevant objects, in particular with a hysteresis.
